CONDUCTOR-POST IORIELECTRIGAIL DISTRIEBUTION.

To all whom, it may concern:

Be it known thatwe, CARL SoHUsrER and CHRISTIAN N. BERGMANN, citizens of the United States, residing at Bellevue and Pittsburgh,respectively, in the county of Allegheny andState of Pennsylvania, have invented certain new and useful Improvements in Conductor-Posts for Electrical Distribution, of which the following is a specifiC&tiOlji.'

Our invention relates to improvements in conducting posts for electrical distribution and isfiparticularly adapted for use with knife switches or for making any-desired connections at both sides of an insulating base, to provide for the direct transmission of electrical currents, either D. C. or A. C.

The object in view is to provide a constru ction having large ampere capacity and ample contact area with the requisite strength, etficienc 'forthe objects in View,

simplicity and c eapness of construction, and, when desired, necessary ventilation In switches of the ler er types, or in bus bar connections or other similar construction, it is desirable toprov-ide good contact area and ample conducting cross section for the current, with means or mounting the conductors and their intervening spacer or spacers on the base, whereby to provide continuous transverse conductors having terminals extending at each side of the base and ada ted for connection in the nianner'intenc ed. i

The present improvements are somewhat similar in construction and'mode of operation, and constitute modifications of and improvements on a. form of similar apparatus disclosed in the prior application of Carl Schuster for improvements in switches, filed,

The. several constructions illustrated are intended for use, upon an insulatin base 2, with a switch 'or bus bar of any suita le form or construction for operation with the elements to be connected by the conductor bar or bars 3, which extend transversely through said base. Said bars are intended for corn nection with any of the well known forms of conducting elements, as a bus bar or 8, switch blade 5, or any number thereof, it being understood that the conductor bars 3 may be also ofany desired number, whereby to present at each side of the insulating base 2, either one or a plurality of parallel se arate attaching or contacting terminals. rdinaril said conductor bars may be mounted wit in any suitable embracing frame 6 mounted u on the base 2 and secured thereon by holding bolts 7, while transverse bolts use, with or rivets 8 extend through opposite sides of' the frame and through. the bars. 3 and through a spacer or'spacers, when such are used, whereby to fixedly secure said-parts in position .on the frame.

As shown in Figs. 1, 2 and 3 of the drawings, the frame 6 is composed of a pair of angle pieces, secured by one leg to the base and by the other leg to the conductor bars and spacer as clearly shown. In the arrangement shown in Fig. 5, the base 6 is composed of similar angle sections, the barembracing portions thereof beinginserted within the transverse cavity through the base as shown, and secured to the bars and base in the same manner by bolts 7*.and rivets 8. The spacer 9 and 9 is of any suitable construction, but in the form shown in said figures, is provided with opposite parallel faces for engagement with the in-- ner. sides of the conductor bars and recessed at one or both sides as indicated at 10 and 10 respectively, whereby to permit of ample air circulation.

erable in the use of A. G. currents, whereby to provide for ample exposure of the, con

ductor bars and the avoidance of eddy currents, etc.

It will be understood that the spacers are ductor bars and their terminals, where straight barb are used; also that the spacers may be composed of one or more parts laid side by side or assembled in any suitable manner, whereby to provide for adjustment of-the lateral spacing of the bars, convenience in assemblage, etc., as by forming the spacers of a plurality of'pieces 9 having inclined o1- wedge-like inner faces as iudicated in Figs. 7 and 8, or by forming their confronting meeting faces of curved surfaces, convex and concave respectively, as indicated at 9], Fig. 9. With either of such forms,the parallelism of their sides or faces which make contact with the inner sides of the conducting bars is maintained, whereby to insure the parallelism of the bars and correct fitting and nyounting on the base. Also, by adjustment as the wedge spacers,

the conducting bars may be adjusted later- ,ally to provide the desired intervening space.

In some cases, we may entirely eliminate the spacer or spacers by mounting the bars within a frame or frames suitably constructed to maintain the conductor bars in fixed operative position, as by the construction shown in Figs. 10 to 15 inclusive. In such case, the base 6" maybe provided with suitable attaching flanges if desired, or merely made in rectangular shape as in Figs. 18 and 13 having a flat bottom portion whereby to secure it to the insulating base b the bolts 7, and an outwardly projecting ranie portion having at its opposite inner sides Such construction is prefbe provided between the con-.

comprising laminae of undiminishe or ends vertically arranged receiving grooves 11 for the edges of the conductor ars. The frame may be made in a single piece as shown in Figs. 10 and 13, or may be composed of two end pieces 6' having similar grooves 11, space apart at eac opposite edge of the conducting bars, and secured to the base in the same general man-J nor, as in Fig. 11.- If desired, the conductor in Fi s. 13, 14 and 1,5 may have opposite shoul ered portions 12 adapted-to extend downwardly into cross receiving slots 11' in the top portion of the base, in which case the outer portion with the outer edges of the wider portion of the bars 3.

In Fig. 12 the base 6" is of one piece of metal having transverse slots 11 which may be of the full width the ends, with the intervening spacer section 9 with one or more holding rivets 8 fixedly holding the bars in place. With either construction, the bars are positively held in proper spaced relation to each other 90 and are rivets.

In the arrangement shown in Figs. 16 and 17, the conductor bars 3 are adapted for mounting in any of described and may be spaced apart by Spreaders 9 in the form of washers, disks or in fact separating elements of any other suitable form, adapted to fixedly space the fixedly secured by the transverse conductor bars apart and to provide for air 100 circulation. The spacers may also be in the form of longitudinallly disposed sections of wire arranged as in icated at 9', Fig. 18,

between the conductor bars 3, and in either of said various arrangements ample clcar- 1 5 ance space is also provided for the trans verse holding rivets whereby the bars are positively connected with the base, if'necessary.

in any of the various forms and arrange- 110 monts above described, or with any obvious equivalent thereof, we provide for a positive, rigid mounting of the contimlous conductor bars which extend through the insulating base from. one side to the other, broad area and carrying capacity for the current and efficient connection with switch blade, bus bar or other elements, the conducting bars and their spacer or s acerl and contact surface, coextensive with the area of the conducting elements with which they are connected. The conductors as thus mounted and arranged are maintained in separate relation to each other and the en- 125.

tire construction constitutes one-piece laminated post;

In Figs. 19 and "20 we show a single flat thin conducting bar 3 adapted for connecpracticllly 1 tion at either end with' a switch blade, bus

bars 3' as shown of the base may be flush of the bars and open at the base supports above having area tending through the base,

capacity, esp'eciall' bar, or other suitable conductor. As shown,

the bar passes through the insulating base 1 2 with ample clearance space for air circulation between the bar and base, and is fixedly mounted in the receiving grooves 11 of frames 6 and held by the rivets 8 The frames are secured to the base by bolts 7 and whenso mounted the conductor bar is capable of transmitting a maximum ampere y of i current and has the several :l"lVz\ []lrl;uS noted.
